The pump house will hold the pumping system needed to activate the whitewater channels.

From the Program Manager

Crews poured 580 cubic yards of concrete this week as work continued on the MAPS 3 whitewater facility, which will be known as Riversport Rapids. The slab, which is 110 feet wide by 165 feet long, will serve as a floor for the bottom pool of the whitewater channels. Foundation work for the main building continues as well as other site and utility improvements. Riversport Rapids is scheduled to open in 2016.
